Helps Valve Manufacturer Improve Customer Satisfaction

A leading manufacturer of butterfly valves in India press fitted the EPDM rubber seals on to the powder coated cast iron body of the values using press fit. The seals was pushed into the groove and expected to stay in place due to friction. However, the customer found that during operations the seal would tend to come off causing leakage, rework and resultant customer dissatisfaction.

Eliminates Need for Expensive Machining

A leading manufacturer of industrial cleaning equipment in India developed a new model of portable cleaning machines. The drive bearing needed to be mounted in the cast iron gear housing. As the Gear housing is cast, it is very difficult to maintain the tolerances. Machining the bearing seat area involved high machining cost and time. The unmachined seat area had gaps to 0.2mm.

Excellent Bonding to Low Surface Energy Polyolefin Substrates Saves Rejections

A multinational customer was planning production of coffee makers for their export markets. Customer used a competitive instant adhesive for bonding the rubber bead to PP (polypropylene) in carafe. Carafe is the glass container used to brew, hold and serve coffee and has a PP top and handle.

Use of Loctite® 770 Allows Adhesion on Inactive Surfaces

A leading manufacturer of electric motors, geared motors, torque limiters, variable frequency drives, soft starters and more in Australia used PP capacitor boxes. Customer wanted to lock threaded plastic parts of these capacitor boxes made of Polypropylene. Customer tested competitive, general purpose adhesives but these fail to perform. PP is a low surface energy material and is difficult to bond.

Replaces Expensive Shrink Fit, Reduces Assembly Time and Costs

Interference fit methods of press fit or shrink fit are commonly used for joining cylindrical parts. The bonding is provided by the friction between mating surfaces. In shrink fit mating parts have a high degree of interference and fit together either by heating or cooling the components. Shrink fit needs requires heating equipment and creates bottleneck in mass production. Further there are risks that during the assembly elastic limits of parts might be exceeded or parts may be deformed.
